The SoQtSpaceball class is the spaceball input device abstraction.
The SoQtSpaceball class is the glue between native spaceball handling and how those events translates to generic events for the Inventor API scenegraph.
enum SoQtSpaceball::Mask |
Enumeration of spaceball input device event types.
Enumeration of spaceball input device types.
SoQtSpaceball::SoQtSpaceball | ( | int | mask = ALL_EVENTS |
) |
Public constructor. The mask argument specifies which events we are interested in.
SoQtSpaceball::~SoQtSpaceball | ( | ) | [virtual] |
Destructor.
void SoQtSpaceball::initClass | ( | void | ) | [static] |
Sets up initialization for data common to all instances of this class, submitting necessary information to the internal SoQt type system.
Reimplemented from SoQtDevice.
SoType SoQtSpaceball::getClassTypeId | ( | void | ) | [static] |
This static method returns the SoType object associated with objects of this class.
Reimplemented from SoQtDevice.
SoType SoQtSpaceball::getTypeId | ( | void | ) | const [virtual] |
Returns the type identification of an object derived from a class inheriting SoQtObject. This is used for run-time type checking and "downward" casting.
Usage example:
void foo(SoQtViewer * comp) { if (comp->getTypeId() == SoQtExaminerViewer::getClassTypeId()) { // safe downward cast, knows the type SoQtExaminerViewer * exviewer = (SoQtExaminerViewer *)comp; } else if (comp->getTypeId().isOfType(SoQtFlyViewer::getClassTypeId())) { // safe downward cast, knows the type SoQtFlyViewer * flyviewer = (SoQtFlyViewer *)comp; // then something else } }
Reimplemented from SoQtDevice.
void SoQtSpaceball::enable | ( | QWidget * | widget, | |
SoQtEventHandler * | handler, | |||
void * | closure | |||
) | [virtual] |
This method will enable the device for the widget.
handler is invoked with the closure argument when an event occur in widget.
Implements SoQtDevice.
void SoQtSpaceball::disable | ( | QWidget * | widget, | |
SoQtEventHandler * | handler, | |||
void * | closure | |||
) | [virtual] |
This method will disable the handler for the device.
Implements SoQtDevice.
const SoEvent * SoQtSpaceball::translateEvent | ( | QEvent * | event | ) | [virtual] |
This method translates from native events to Open Inventor SoEvent events.
Implements SoQtDevice.
void SoQtSpaceball::setRotationScaleFactor | ( | float | f | ) |
This method sets the scale factor for the spaceball rotation vectors.
float SoQtSpaceball::getRotationScaleFactor | ( | void | ) | const |
This method returns the scale factor for the spaceball rotation vectors.
void SoQtSpaceball::setTranslationScaleFactor | ( | float | f | ) |
This method sets the scale factor for the spaceball translation vectors.
float SoQtSpaceball::getTranslationScaleFactor | ( | void | ) | const |
This method returns the scale factor for the spaceball translation vectors.
SbBool SoQtSpaceball::exists | ( | void | ) | [static] |
Returns TRUE
iff there could be a device of this type available on the system.
Note that a return value of TRUE
does not signify that there is such a device active.
Referenced by SoQtRenderArea::afterRealizeHook().
void SoQtSpaceball::setFocusToWindow | ( | SbBool | flag | ) |
Set to TRUE
if you want spaceball events to be received even when the component does not have focus.
SbBool SoQtSpaceball::isFocusToWindow | ( | void | ) | const |
Returns whether or not spaceball events are caught even when the component does not have focus.
